There's a lot of w6:w3 ratio recommendations scattered around the web,
ranging from 1:1 to 10:1. Erasmus himself recommends 2:1, according to
http://www.curezone.com/foods/fatspercent.asp. Mercola recommends 1:1.
Cordain's recent book on the Paleo Diet recommends 1:1, following the
1998 paper by Eaton et al at
http://www.thepaleodiet.com/articles/Eaton%20N3%20Paleolithic.pdf
entitled "Dietary Intake of Long-Chain Polyunsaturated Fatty Acids
during the Paleolithic" which says:
"The w6:w3 PUFA intake ratio during this crucial evolutionary phase
has been estimated at from 4:1 to 1:1; however, the bases for such
estimates have been specified imprecisely, if at all. This paper
presents a further estimate for Paleolithic PUFA nutrition."
...
"In the case of EFA, current intake clearly differs from that of
our ancestors: preagricultural humans generally consumed w6 and w3
PUFA in roughly equal amounts. This pattern fueled the emergence
and development of our genus; evolutionary considerations commend
its restoration."
If the ratio of 1:1 is correct, then it is ONLY flaxseed which makes it
possible to attain the ratio on plant-foods alone. It is arguably THE
crucial ingredient in the success of raw vegan diets (aside from B12).
In that case, your diet is successful because your flaxseed is such a
high proportion of your concentrated fat, and because your conc fat
intake as a whole is pretty low.

Well, the success or failure of your diet seems to me to rest on a single
plant. That's what I mean by "heavy reliance". In contrast, there are
wild animals in just about every part of the world which could serve as an
adequate animal substitute. I didn't say it was impossible to thrive on
a raw vegetarian diet, merely difficult.

To get as much w3 from (say) lettuce as from flaxseed, one would need to eat
approx 500-1500 times as much by weight. So 2 oz flax equates to approx
60-180 lb of lettuce, enough to have a laxative effect on anyone. Maybe
gorillas and horses can get enough w3 from green leaves, but not us.
And our need is relatively greater because our w3-rich brains are bigger.

I agree and I eat a large salad every day which takes me an hour to chew my
way through. But I don't regard it as a significant source of w3.

Surely the fallacy of this is clear if we substitute "B12" for "meat".
I think meat is wrongly valued for its protein-content; the evidence
to me points far more towards its w3-content. And that is not something
that we need daily or even weekly. An w6:w3 imbalance may not show its
effects for years. Its importance to pregnant females and infants, for
the developing brain & nervous system (50% w3), might well account for
its use as a bargaining tool (sex for meat) by male chimps.
>And I don't particularly enjoy the taste of raw meat "as is", anyway.
>Are my instincts telling me something?
I suspect that there are many animal foods that one develops a taste for
in childhood or not at all. Westerners are brought up to eat egg but
not to drink blood, to eat pigs but not dogs, oysters but not insects.
As to why our instincts can adapt more readily to novel raw vegetables
than to novel raw meats, perhaps it has something to do with the dangerous
toxins and parasites that infected raw meat can harbour.

Yeah, perhaps. A bad batch, perhaps. I only tried them 4 times. But I've
rarely had a headache from anything else ...

I'll look her up. I'm not sick, never have been, and I want to stay
that way.

My sentiments exactly.
